VALVE-ACTUATING MECHANISM.

Specification of Letters Patent.

Patented Apr. 4, 1916.

Application filed m 25, 1914. Serial No. 853,138.

To all whom it may 0015mm: Be it known that I, N ILS PE nRsoN; a citizenof the United States, residing at Moscow, in the county of LatahandState of Idaho, have invented a new and useful Valve-ActuatingMechanism, of which the following is a specification.

The device forming the subject matter of this application is afloat-controlled valve for a flushng tank and the present invention aimsto provide, in combination with a float of novel form, a means wherebythe position of the float-carrying lever may be adjusted through theinstrumentality of elements on the stern of the valve.

In the drawingsFigure 1 is a longitudi nal section through the frontwall of a tank showing the present invention in operable relationtherein, a portion of the parts being shown in section to betterillustrate the incased parts. Fig. 2 is a top plan view of the tank withthe complete mechanism therein.

Referring to the drawings, the numeral 1 designates a casing which isopen at the lower end to receive a bottom member 2 which carries a metaltank 3,'set screws 2' being provided to lock the bottom 2 and the tank 3within the casing 1. i

The flushing pipe 4 of the present mechanism is provided with a seat 5for the reception of a buoyant valve 6, preferably made in the shape ofa hollow rubber ball. A tube 7 is connected to the seat 5 andconstitutes an overflow directing member, the

open upper end of the tube being located above the highest water levelin the tank 3,

I the lower end of the pipe 7 being in communication with the pipe 4below the valve seat 5. A stem 11 is carried by the ball 6 and isdisposed in cooperating relation with a stem 10 connected to the innerfree end of a lever 12, provided with a we ght 16 which assists in theseating of the valve 6. The lever 12 is pivotedat 13 so that its free.end may be depressed by' a manually controlled lever 15, which isaccessible from the exterior of the tank 3. 1

A supply pipe 18 is connected to a coupling member 19 which is providedwith an inverted valve seat 20. A casing 21 constitutes a stand pipe andsupporting member, and is connected upon the inner side of the tank 3 tothe coupling 19, the casing 21 being provided with a spout 22,which isin communication with an overflow outlet 23. A tube 9 is connected tothe spout 22 and has 1ts terminal 8 disposed within the upper end of thetube 7 so that the after flushing water may be directed into the tube.

A tube 21 is connected to and forms an upward extension of the casing 21and constitutes a guide for a valve stem or rod 25 carrying upon itslower end within an enlarged portion of the supply pipe 18, a valve 26for controlling theseat 20. The upper end of the stem 25 is threaded andextends be'-,

yond a coupling 27 mounted on the tube 241, the couplmg being providedwith two upstanding arms 28 and 29. The arm 29 is provided with anaperture for the reception of a pin 30 which forms a fulcrum for a lever32, receiving the threaded end of the stem 25. The threaded end of thestem is adjustably connected. to the lever 32 to cause the rise and fallof the valve 26, by means of nuts 33 and 3-11. A link 32 connects thelever 32 with a lever 31, the latter being fulcrumed on the arm 28. Aweight 35 is adjustably mounted along the lever 31, and

adjustably connected beyond the lever is a sleeve 36 carrying an ovoidalhollow float 38, which has freely movable therewithin, a plurality ofrolling elements 39, which may be inserted into the float 38 through anopening 50 in the top of the float, the opening 50 being closed by a cap51.

It will thus be seen that when the ball valve 6 is elevated by thelevers 12 and attendant parts to release the water within the tank, thefloat 38 will move downwardly and consequently lower the valve 26 topermit water to enter through the spout 23 into the tank 3. When theball valve 6 automatically seats, the water within the tank will risedue to the entrance thereof through i the spout 23 and will graduallyelevate the float 38 and operate the lever 31 so as to bring the valve26 gradually toward the seat 20.

The number of weights 39 within the float 38 may be changed as occasionmay demand, the opening 50 and the cap 51 being of use for this purpose.

What is claimed is:

In a device of the class described, a tank; an inlet valve casingassembled with the tank, the casing having a valve seat and beingprovided with an outlet discharging into the tank; a valve controllingthe seat; a

10 being adjustable to vary the relative positicn of the lever mechanismand the float when the valve is engaged with the seat.

In testimony that I claim the foregoing as my own, I have hereto affixedby signature in the presence of two witnesses.
